He really is Hollywood royalty! Leonardo DiCaprio sups from a golden goblet as he enjoys guys’ day out at US Open

He spent part of the summer sailing around the Mediterranean with his girlfriend and Leonardo DiCaprio isn’t quite ready for his vacation to end.

After returning to New York last month, Leonardo was spotted at the US Open on Tuesday with his actor pal Lukas Haas, where they watched Serena Williams easily beat Carla Suarez Navarro 6-0, 6-0 in the quarter finals.

And while the players worked hard on the court, DiCaprio, 38, was happy to sit back and relax as he drank from a gold goblet and enjoyed a cigarette.

Dressed down in a navy polo shirt and khaki trousers, Leo tried to keep his identity hidden with a newsboy cap and large sunglasses.

However, his fellow spectators clearly recognised him and at one stage the Great Gatsby star shared a joke with the woman in front of him.

There was no sign of his 21-year-old girlfriend Toni Garrn, who recently became the latest in a long line of Victoria’s Secret stars to date the Oscar nominee.

Despite the 17-year age gap, the pair appeared to be smitten during their summer holiday in Europe.

They reportedly hooked-up at the Cannes Film Festival in May and the multi-millionaire superstar spent some time showing his new romantic interest around Europe.

In June, he whisked Toni away to Venice, Monaco and then to France, where they took in sights such as the Palace of Versailles.

Meanwhile, the talented actor was recently reported to have landed a leading role in the historical mystery-thriller The Lesdiguieres Legend, which is currently in pre-production.

Earlier this year, he completed work on The Wolf Of Wall Street for director Martin Scorsese opposite Matthew McConaughey.
